There's a list of "bite size" projects here, which are a good place to


For the weighting schemes project, trying to add support for an
additional normalisation to TfIdfWeight would help give you an idea
of what's involved.

Have you successfully built the latest xapian-letor?  I think the one
from the 2012 GSoC branch is probably the best starting point, but Parth
can probably give more insight into the current state of things.

There's a xapian-letor on trunk, merged after GSoC 2011, which isn't
built by default.  If you "rm xapian-letor/.nobootstrap" and rerun
the bootstrap script, it should get built.
